Potential role of medicinal plants against Alzheimer’s disease

Abstract

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder of the brain which leads to a decline in memory and cognition. The Food and Drug Administration (FDA) approved medications provide only symptomatic relief and are often associated with adverse effects. Many natural products have shown their activities against AD. Bioactive compounds like polyphenols, tannins, alkaloids, flavonoids, terpenes, sterols, etc are present in various plants. These compounds have shown antioxidant, anti-inflammatory, anticholinesterase, and anti-amyloidogenic activities. This review article discusses the benefits of various plants against AD.
